History
In the late thirties, the British Royal Air Force was in the process of re-equipping its bomber units with new, high performance monoplanes. The goal was to outperform existing fixed gear fighter biplanes, such as the Hawker Fury and Gloster Gladiator. Bristol contributed a design for a twin engine monoplane called “Britain First”. This airplane was privately financed by Lord Rothmore, and was intended primarily as a business executive plane. The RAF tested the type, and was impressed, so after considerable redesign, the type emerged as the Type 142 bomber. Tests were completed by 1936, and full production was ordered under the name Blenheim Mk. I.
